JPS606241Y2 - Footwear outsole sheet piece - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an oversole sheet piece for footwear.

More particularly, the present invention relates to an overlay sheet piece for footwear, including slippers, sandals, geta, sandals, shoes, shoe insoles, tabi socks, and the like.

In the first place, the current situation is that subsequent users of slippers, for example, which are used by an unspecified number of people, are forced to use slippers that have been soiled by previous users.

In the current situation, subsequent users have no way of knowing about the foot hygiene of previous users.

The present inventors developed the present invention in order to deal with such unhygienic conditions.

The overlay sheet piece of the present invention has a removable pressure-sensitive adhesive coated continuously or discontinuously on the back surface of one side of the sheet body, so that the adhesive layer is applied to the bottom surface. Then, it can be attached and fixed to the surface or front/bottom surface of any footwear in a so-called pressure-sensitive manner depending on the increase in weight during use.

For this reason, even if this paper is made of thin paper, it will not shift, wrinkle, lose its shape, or fall off during use.

Moreover, it has the advantage that it can be easily renewed by peeling off if it becomes contaminated.

There is no particular limit to the thickness of the overlay sheet piece body of the present invention, but for example, it is 0.2 to 31 feet! It can be formed of preferably porous breathable and hygroscopic thin paper, kraft paper, thick filter paper, cellophane, cloth, knitted fabric, felt, nonwoven cloth made from a synthetic resin sheet, etc., preferably having a porous air permeability of about n.

Then, a peelable pressure-sensitive adhesive is applied continuously or discontinuously to the back surface of one side of the overlay sheet piece, either entirely or locally.

The overlay sheet of this invention absorbs moisture (humidity) and sweat secreted from the soles of the feet and has thermal insulating properties, so you won't feel cold, and it will always stay dry, making it comfortable and hygienic. be.

In particular, if it is impregnated with, for example, an athlete's foot disinfectant, it can also be used as a sanitary agent.

The overlay sheet piece of the present invention can be used not only for specific footwear for individuals, but also for footwear such as slippers that are shared alternately by an unspecified number of people in hospitals, hotels, inns, passenger seats, toilets, bathrooms, etc. Can be recommended.

In these cases, you will not feel uncomfortable even if you wear them barefoot.

The present invention is characterized by the specific use of pressure-sensitive adhesives.

Here, the pressure sensitive adhesive is clearly distinguished from various known adhesives or pastes that are intended for permanent adhesion in that it is releasable.

Pressure-sensitive adhesives that can be used include water-soluble ones such as polyvinyl methyl ether, water-insoluble ones such as polyvinyl ethyl ether and isobutyl ether, other synthetic resins, natural rubber, etc., organic solvents, and emulsifiers. or polyisobutylene in combination with natural rubber, tackifying resin, butyl rubber, chloroprene rubber, vinyl chloride-vinyl acetate copolymer, chlorinated rubber, polybutyral, etc. You can.

These are applied as a suitable solution to a thickness of about 0.01 to 0.1 rrarL by brushing, calendaring, spraying, etc., over the entire surface or locally on one side of the sheet piece.

The footwear insole sheet piece of the present invention is provided in shapes of various sizes adapted to the shape of the surface area of any footwear to which it is applied, for example as shown in the accompanying drawings.

1 and 2 are plan views of a sheet piece in which a pressure-sensitive adhesive 2 is locally applied to an overlay sheet 1.

FIG. 3 is a plan view of the pressure sensitive adhesive 2 applied to the entire surface.

FIG. 4 is a sectional view taken along the line A-A' of the sheet piece shown in FIG.

FIG. 5 is a sectional view taken along the line A-A' of the sheet piece shown in FIG. 3.

Incidentally, FIGS. 1 and 4 relate to sheet pieces for sandals, slippers, and shoe insoles.

Figure 2 is for tabi socks.

Figures 3 and 5 show sheet pieces for geta and sandals.

In use, the layer of adhesive 2 is placed on the bottom side.

As a result of experiments, the pressure-sensitive adhesive of the present invention was applied to a width of 3TrI instead of being applied entirely on one side of a sheet piece of the above shape!
One thread or several parallel threads of n~1oTrIn (including diagonal lines)
I have found that it is sufficient to apply it to the tips, middle and/or back (heel area).

In this way, the present invention is extremely practical and useful because it can be easily removed when updating.
